The SLC30A3 gene codes for the ZnT-3 SLC30A family membrane transport protein. ZnT-3 is required for the accumulation of zinc ions inside synaptic vesicles.^[6] In mice, ZnT-3 is required for some forms of memory that depend on the hippocampus and the amygdala.^[7] Zinc transport by ZnT-3 modulates memory formation by acting through the extracellular signal-regulated kinases signaling pathway.^[8] Angiotensin II-induced senescence of vascular smooth muscle cells requires down-regulation of ZnT-3 and ZnT-10.^[9]
